Re: Gear Ratio Question

[beerman57]

Dan, guess what I’ll be doing if I use the smaller gearcase, that’s right – disassembling the big case again to get the D/S (haven’t checked part numbers yet, but if I remember right, the D/S will work in both). But my original question, will the 2.4:1 ratio (big case) be that much better than 2.66:1 (small)? When you multiple that by 5000 or so RPM’s, it might make a big difference – like about 320 prop revolutions in one minute (5000rpm divided by 2.4 versus 5000 divided by 2.66). That’s over 5 prop revolutions per second at only 5000rpm, starting to sound like a big performance difference to me, if my thinking is right.
